I don't remember the 1960 one but I lived through an ice storm in Dahlonega, GA. in 2000. The ice was so heavy on the power lines that it bent the steel power poles. Not the regular one pole power pole but the big ones that have a base with 4 legs. We were without power for a week and a half. The only heat we had was the gas oven. Yeah I know not safe but it was 18 degrees outside.
